Abstract
A system and method for determining a layout of an electronic document containing bidirectional Hebrew text is disclosed. The system and method have a layout filter configured to determine if the electronic document is a candidate for layout detection based upon features of the electronic document, and an encoding detector configured to determine the encoding employed to encode characters in the electronic document; and an ordering detector configured to determine, based on the determined encoding, an ordering scheme employed in the electronic document. Additionally, a base direction detector configured to determine, based on the determined ordering scheme, a base direction of the electronic document based at least on non-Hebrew characters present in the electronic document; and a mirroring detector configured to determine a character mirroring state for the electronic document based upon the ordering scheme and a presence of at least one bracket pair in the electronic document.
